Open the CIPO recordAbstract From the Canadian patent
A stent is covered by a continuous covering layer of elastic material. A roll on surface is treated with a lifting medium, and then coated with an elastomeric polymerisable composition dissolved in a sufficient amount of solvent to permit contact forming. At least a portion of the stent in expanded condition is rolled on said coated roll on surface. Withdrawal of the stent from the roll on surface is followed by evaporating the solvent, and polymerising the elastomeric composition adhered by contact on said portion of the stent.

Why it's free to use
- Filed February 3, 1994 and granted September 14, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 3, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 3, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
